Abstract: An apparatus relates generally to an injection-controlled-locked phase-locked loop (“ICL-PLL”) is disclosed. In this apparatus, a delay-locked loop is coupled to an injection-locked phase-locked loop. An injection-locked oscillator of the injection-locked phase-locked loop is in a feedback loop path of the delay-locked loop.
